Abstract(in Japanese) (See Japanese page)
Abstract(in English) Human can communicate not only by conversation but also by gesture. To investigate features in a movement to achieve communication, skilled conductor's movements were analyzed by numerical simulation and human arm movements that are easy to perceive the rhythm were examined by psychophysical experiments. As a result, it was suggested that essential constraints to generate the conductor's movement are condition of velocity near the lowest position of hand path. Based on this result, movement trajectories calculated by optimization of the cost function with constraint of velocity could represent conducting. As a result of rhythm perception experiments, it was found that the essential element of communication by gesture in the orchestra is a part of arm movements against the performance index about smoothness like torque change.
